Thanks for starting this topic, Varon.
In my personal experience with sci-fi, I have always taken "robot" to be a very generic term, of which "android" is a specific subset that implies a robot with extremely advanced AI and human appearance. When I hear "android," I assume it is a robot made to look and act as human as possible. Consequently, I expect an android to either replicate human emotions or be attempting to.
Androids possessing human emotions is a sci-fi trope all its own, and one I'm rather fond of myself. I love a good humanesque android, whether it's taken for granted or accompanied by the usual "Can a robot have human emotions?" debate. Never gets old for me.
And there's quite a bit of both story and emotional potential with human-like robots. Astro Boy is a great example of this."Cyborg," on the other hand, I take to mean a human augmented with robotic parts. While an Android is definitely a robot simply made to look human, I usually assume a cyborg began as a human. There seems to be a pretty wide range of what makes someone a cyborg, however; it can be anything from a few simple robotic implants to practically being a walking suit of armor. I like myself a good cyborg implant, too.
In the steampunk fairytale world Grace and I are creating, crossing human life with robotics is considered a sin. Therefore, while they have extremely advanced AI, creating an android that looked nearly human-like would be considered scandalous. And any human who receives a robotic implant of any kind is ostracized. Fun stuff.
